The Sleipner.
A Sleipnir is an 8-legged mythical magic horse.
Just age your horse to twenty months or 1 year 8 months
There are no such thing as 4 legged spiders. If there were any, then they wouldn't be called a spider! A spider has 8 legs. :)
click the ultrasound button under reproduction when you are visiting your pregnant horse
You can age the horse with ageing points - click "age my horse" to the middle left of your horse's page and age him 2 months without waiting. Or, you can simply wait until the next day when the horse will have aged naturally.
Yes. If the horse is 6 months into her gestation period and you age her with an aging point, she will be 8 months into her gestation period.
It takes 8 months so 4 days or just use aging points
You cannot make your horse a Sleipnir, they are divine horses with 8 legs and you must buy them as there is no longer the promo where you can win them.
You can have an ultrasound at 6 - 8 months, but they are not worth it in all honesty. Better to save your equus for the birthing cost.
